The south facing slopes which loom above are a wintering area of primary importance for the chamois and ibex. In winter 2015 there were approximately 120 ibex and 150 chamois. Two survival strategies exist: the ibex holds on to its fat reserves, remains inactive and has additional feeds (it loses up to 30% of its weight in winter!), while the chamois has a metabolism that requires meals almost daily, hence its presence in the avalanche paths where snow clearing occurs naturally.
